I know it's pretty important to get a quality wall mount for something as expensive and important as a flat panel TV, but I bought one of these because of the price and the reviews on the site and I couldn't be happier. I put it on the wall and it held all 230 pounds of me, so my 58" 100+ pound TV should be OK. Granted I was only looking for one of the tilting one and not one of the full motion mounts, but take a look to see if they have what you want. Prices are great, but it will cost about 20 bucks for shipping (I'm guessing you'll probably pay this on your mounts too if you order them online).
